What is the fluid deprivation test for diabetes insipidus?
A doctor has provided 1 answer
Vasopressin test.: This is a dehydration test for diabetes insipidus. First, fluid is withheld until urine osmolality is stable. Then 5 u of vasopressin is given by subcutaneous injection. The urine and plasma osmolality/concentration is measures before and one hour after the injection. Argenine vasopressin or avp given to these patients causes a >9% rise in urine osmolality. In normal patients, it is <9%.
